EarthScope

GeoEarthScope, a part of the EarthScope Program funded by the National Science Foundation, includes the acquisition of LiDAR topography to examine the strain field beyond the decade time scales available from the PBO geodetic instrumentation. A goal of EarthScope is the improved understanding of the tectonic evolution of the North American continent.  LIDAR data acquisition campaigns took place in 2007 and 2008 and cover a total area of nearly 5,000 km².  All data will be delivered via OpenTopography and will be made available to the community as soon as it is processed.

Use of these data should be acknowledged with the following language:
This material is based on services provided by the Plate Boundary Observatory operated by UNAVCO for EarthScope (http://www.earthscope.org) and supported by the National Science Foundation (No. EAR-0350028 and EAR-0732947).

B4 Project LIDAR

The “B4 Project” collected LiDAR point cloud data of the southern San Andreas and San Jacinto Faults in California.  Data acquisition and processing were performed by the National Center for Airborne Laser Mapping (NCALM) in partnership with the USGS and Ohio Stuate University through funding from the National Science Foundation (NSF). The B4 Project has kindly agreed to make these data available to the research community through the OpenTopography Portal.

Northern San Andreas & West Rainier

This airborne laser swath mapping data was acquired in support of collaborative research by members of the U.S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA), with funding provided by NASA’s Earth Surface and Interior Focus Area. The data were acquired and processed by TerraPoint, LLC under contract to NASA’s Stennis Space Center. The data are in the public domain with no restrictions on their use.
